My latest video for TurfNet.com is live. In this video I discuss the "Chest Harness" for use with portable 2-way radios. These were a big help during my career as a golf course superintendent. They are very comfortable and offer many benefits. Check it out, click HERE to view. As always, thanks to my supporting sponsor, Tanto Irrigation

Presenting in Buffalo, NY

My first ON COURSE video of 2019 for TurfNet.com is live. In this video I discuss the "due diligence" needed during the planning stages of a new irrigation system. I talk about the "other" components besides the irrigation controls and sprinkler heads. Check it out, click HERE to view. I would like to also welcome back my supporting sponsor for 2019, Tanto Irrigation Thanks for your support! 

TurfNet Webinars....

I've been catching up on some TurfNet.com webinars lately and realized what a benefit it is to have these available online. I missed a number of these this past year due to some extensive traveling. Having these available in an archive is absolutely the best. Thanks to Grigg for sponsoring these great educational webinars. This webinar by Dr. Doug Soldat, Fundamentals of Fall Fertilization, I found really interesting. I know it's not fall, but if you haven't viewed this webinar it's a must for all turf managers. You can view it HERE

My Latest Read....

A few years ago Jim Haley, Highland Golf Services stopped in my office with Bill Bartels, Tanto Irrigation and gave me a copy of "Dream Golf" The Making of Bandon Dunes. Well, about that time I was slowing packing up my office for my eventual retirement from the golf course superintendent profession and this book was immediately packed. Well, after 3 years in a box and in storage, it was recently unpacked and moved up to the top of my read list. Can't wait to read the whole story. Thanks Jim for the copy. 

Visiting and touring Bandon Dunes was one of my true highlights
 of my golf course management career.

My latest ON COURSE video for TurfNet.com is live. In this video I chat with Dennis Kling, Golf Course Superintendent for the City of Loveland, Colorado. We discuss in specifics the Cattail Creek mini-course. This course was built to help "Grow the Game" of golf. It uses SNAG golf equipment and is a fantastic way to introduce young kids to golf.

Vole Control on the Golf Course

There is no debating the fact that one of the biggest issues for superintendents in the mountain west are those little pesky voles. Voles are rodents and a relative of the mouse. There are over 100 species of voles. The meadow vole is responsible for the bulk of the damage in a turfgrass situation. Voles are herbivores and the majority of their diet consists of grass stems and leaves. In the summertime voles migrate to thick taller grassy/native areas for protection against predators. However, when snowfall arrives they have protection under snow cover and this is the time they migrate to fine turf areas and can cause damage. This makes golf course turfgrass very susceptible to damage during wintertime period. Voles cause turf damage by chewing grass plants extremely low to the ground. They chew so low they cause damage to the crown of the plant. Voles also create runways in the winter, first by chewing the plants, then by using these to forage for additional food each day. These runways can see extensive traffic throughout the winter as voles forage each day on 10-15 trips through these runways.

Generally speaking, voles don’t directly kill the turf plant. Although if they damage the crown of the plant extensively, it is possible. The main issue with vole damage is the slow recovery of the turf in the spring. With the combination of cold soil temperatures and damaged turf plants in the spring, recovery can be extremely slow. The other issue with vole damage is its effect on playability. When a golf ball lands in one of the vole tunnels it can nestle down and make for a very poor lie. So until complete recovery occurs playability suffers.

 an application of Milorganite and sand topdressing and is not touched!

Controlling voles is extremely difficult if not impossible. Over the year’s superintendents have tried many different products with minimal success. One product I found which shows some vole repellency is Milorganite fertilizer. I discovered this primarily by accident. I have used Milorganite fertilizer for many years as a dormant feed on greens, tees, and fairways. What I didn’t realize was all those years of apply Milorganite, I was also repelling voles in those areas. 

All the years we applied Milorganite to the fairways we were getting
a side benefit of vole control, which we really discovered in 2014.

This came to light during the winter of 2014-15. That fall we had early snow cover and only finished 11 fairways with our Milorganite application. That spring we had extensive vole damage on fairways that didn’t receive the Milorganite application. We also noticed that spring that late season topdressing applications also reduced vole damage. With this in mind, we decided to apply Milorganite to the rough as well in the fall of 2015. We also set-up some small test areas with check plots to test our theory.

Some testing I performed in some grassy hollows which every year suffers
from vole damage. No Milorganite applied on the left and 0.75#N/M applied
to the right. Totally clean from any damage with the Milorganite.

In the spring of 2016 we were amazed at almost the complete lack of vole damage on the property. Our test plots also show without question that Milorganite certainly repels vole activity. We used a rate of 0.75#/N/M in all the rough and in our test areas. The results were fantastic. With this in mind, ONCOURSETurf, LLC set-up some independent testing in the fall of 2017 at some other local golf facilities, Sonnenalp Club and Red Sky Ranch. All test plots were 25 square feet and received a rate of one pound of nitrogen per 1000 square feet. Plots were established in areas of consistent vole damage each spring. Most areas were north facing, which allowed prolonged snow cover. In mid-April this past spring after snowmelt, I was able to observe the results from those test plots. The past winter season was a low pressure vole year, meaning the voles were not as active as other years. The main reason for this was the lack of snowfall and the lack of duration of what snow was received. With voles primarily active under snowcover. No snow cover equals no voles. There was some snow cover however and we did see some positive results with the Milorganite use. The rate used for the test plots was 1#/N/M. Take a look at some of my findings below.

Voles active in the area, but the Milorganite plot stayed clean from any damage.

In this test plot we had heavy vole damage on two sides, but the plot was generally clean.
The arrow shows vole entry into the plot from the right side, but it appears there was
repellency as very minimal damage occurred.
  

Another observation from the test plots was spring green-up. At the time of the test plot observations, soil temperatures were in the high 30's. In the photos below you can already see some spring green up occurring even with these extremely cold soil temperatures.

Initial spring green-up noticed immediately after snowmelt with soil temperatures in the high 30's.

Although it wasn't a high pressure vole year, there were certainly some indications that Milorganite can be effective for vole repellency. Presently, I am in the process of establishing some new testing on some of Colorado's front range courses to study this repellency further. Stay tuned.
Special thanks to Milorganite and WinField United for their support in establishing these test plots. 

To summarize, Milorganite certainly shows some control for vole damage. This fertilizer is a great option for a dormant fertility program with getting additional side effects of vole repellency. Getting two things accomplished with one product, that is a big plus!
